“…Row covers are most popular with organic and conventional growers in cropping systems that have a very low tolerance of insect damage. There is very low tolerance for insect damage where insects are causing direct damage to the produce such as in brassicaceous leafy greens [ 14 ], lettuce [ 32 ], and apples [ 46 ]. Additionally, there is very low tolerance for insect pests in crops where insects are vectors of plant pathogens such as whiteflies in tomatoes [ 47 ], cucumber beetles in cucurbits [ 38 ], and aphids ( Aphis gossypi Glover, Myzus persicae Sulzer), whiteflies, and thrips species in hot peppers [ 48 ].…”

Brassicaceous leafy greens are an important crop for small growers but are difficult to produce due to damage by flea beetles. Flea beetles are problematic for growers as they chew many small holes through leaves rendering produce unmarketable. We tested the efficacy of several essential oils, the woven-mesh row cover ProtekNet, and the spunbonded row cover Agribon, compared to organic and conventional insecticides and no spray controls in the spring and fall of 2019. We found that the two row cover treatments (Agribon and ProtekNet) provided the best control of flea beetles and associated damage. Thyme oil was highly phytotoxic and killed the crop entirely and rosemary and neem essential oils caused mild phytotoxic burns. Organic insecticides rarely performed better than the no spray control. While conventional insecticides controlled most flea beetles, the crop was often still too highly damaged to sell. The results of our study suggest row covers offer producers an effective method of flea beetle control that reduces their dependence on insecticides for conventional and organic production.

“…Indeed, the nets hamper the flight of male moths during their approach towards females, reducing mating success, and may cause visual disturbance in searching males . Even if C. pomonella and G. molesta were not very abundant in the surveyed orchards, our trials confirmed the effectiveness of the nets against these moths, as well as against S. myopaeformis collected thanks to the feeding attractant added in the C. pomonella pheromone traps. In our trials, the number of damaged fruits was too low to assess the effectiveness of the used net in containing C. pomonella damage, as reported by other anti‐hail nets…”

BACKGROUND Frequent pesticide treatments in fruit orchards increase hazards for workers, consumers and the environment. Moreover, the indiscriminate and excessive use of pesticides often induces resistance in pests. In the past few years, physical exclusion strategies have been proposed as an alternative for the control of insect pests. The goal of this study was to evaluate the effectiveness of anti‐hail photoselective netting in protecting apples against key and emerging pests, as well as the impact on beneficial arthropods, fungal diseases and fruit quality. RESULTS In netted plots, a significant reduction in pest populations, i.e. fruit moths, Halyomorpha halys (Stål) and Drosophila suzukii (Matsumura), was recorded in comparison with un‐netted controls. Moreover, the damage on fruits caused by H. halys was reduced up to 62% compared with insecticidal treatments. The net did not negatively affect the abundance of predators and the incidence of post‐harvest rot. In addition, the incidence of bitter pit on apple was reduced up to 52%. Furthermore, fruit quality was unaffected by the net coverage (both at harvest and after 4 months of storage). CONCLUSION Anti‐hail photoselective pearl netting proved a promising exclusion system that can prevent attack by more than one insect pest at a time, allowing for a strong reduction in insecticide treatments and relative costs. At the same time, the netting did not negatively influence the presence of predators, the incidence of fungal disease or fruit quality. © 2019 Society of Chemical Industry

“…The net support structures were installed in early April 2016, based on the complete exclusion netting system described by Chouinard et al (2017) in order to create a hexagonal tunnel to hold the net away from the branches ( Supplementary Fig. 1).…”

“…The structure characteristics of exclusion systems have also been adapted for fruit trees, and their effectiveness appears promising for reducing the need for insecticides, as nets provide an impenetrable barrier against harmful pests. In Quebec apple orchards, exclusion netting systems are generally installed in a row-by-row design and are closed above the base of the trunks with clips (Chouinard et al, 2016(Chouinard et al, , 2017. The soil is therefore excluded from the system, which prevents the development of most pests [e.g., codling moth (Cydia pomonella), apple maggot (Rhagoletis pomonella) and plum curculio (Conotrachelus nenuphar)] that complete their life cycle in the soil or at the base of the trunk (Agnello et al, 2006).…”

“…Exclusion netting systems appear to represent a good alternative to insecticides and may become the norm for organic orchard management in the future (Chouinard et al, 2017(Chouinard et al, , 2019. Currently, nets must be opened for a few hours on 2-3 suitable days during bloom to ensure successful pollination by honey bees and adequate fruit set.…”

Exclusion netting systems are effective in various contexts and are increasingly used to control crop pests. However, factors affecting pollination management under nets are poorly known. The pollination effectiveness of commercial bumble bee hives of Bombus impatiens Cresson (Hymenoptera: Apidae) was studied for apple production under exclusion netting systems in a research orchard located in Quebec, Canada during 2016–2017. Sixteen single-row plots of apple trees (plot length: 18.5 m, cultivar GingerGold) were subjected to one of the following four treatments during bloom: (1) introduction of a bumble bee hive placed at the end of the row, under nets; (2) introduction of a bumble bee hive placed in the middle of the row, under nets; (3) negative control with no pollinators, under nets and (4) agronomic control with nearby bee hives (<50 m), without nets. Resulting post-harvest fruit quality (e.g., fruit weight, size, number and distribution of seeds) was evaluated, as well as correlations between bumble bee visitation rates and fruit quality parameters were evaluated. Results suggest that bumble bees provided adequate pollination under exclusion netting systems and that resulting fruit quality was equivalent to that of apple fruit conventionally pollinated by honey bees and wild bees community (bumble bees and other bees) in the orchard environment. Positioning bumble bee hives in the middle of the row provided better fruit load homogeneity in pollinated trees. Additional discussion on bumble bees as apple pollinators and on pollen distribution methods is also included.
